About Johnny

Développeur .NET senior avec 10+ ans d'expérience, je construis des solutions robustes, testables et maintenables.

Tests & Qualité : Spécialiste du Test-Driven Development (TDD) et du Behavior-Driven Development (BDD). J'ai introduit ces pratiques dans plusieurs organisations et formé des équipes à leur adoption. Mon expertise en tests automatisés (unitaires, intégration, E2E) est régulièrement un facteur décisif dans l'obtention de missions.

Architecture : Je conçois des architectures propres et évolutives : microservices, systèmes distribués, messaging (NServiceBus, RabbitMQ). Je privilégie la simplicité, la séparation des responsabilités et les décisions techniques documentées.

Clean Code : Adepte des principes SOLID, du Domain-Driven Design et du refactoring continu. Je livre du code lisible, testé et facile à faire évoluer.

Mentorat : J'accompagne les développeurs juniors et seniors dans leur montée en compétences : pair programming, revues de code bienveillantes, ateliers techniques. J'ai animé des sessions hebdomadaires de partage de connaissances chez plusieurs clients.

Secteurs : Finance, Santé, Services Publics.
